To all .whom t may concern:

Be it `known that I, Brenner E. VV1GLEs- WORTH, a citizen of the UnitedStates, residing at Marye, in the county of -Spottsylvania and State ofVirginia, have invented certain new and useful yIrnproveinents in Grain-Separators, of whichthe following is a specification.

This invention relates to a combined grain separator and straw baler andit has for its object the provision of a devicev of this characterconstructed in such manner that the straw baler will be operated inunison with the grain separator, the straw will be delivered directlyfrom the separator to the baler,

rthe separated grain will be thoroughly cleaned and the chaff removedtherefrom and the chaff will bedelivered into the baler with the strawso that `the straw and the chaff will be baled together.

It is a further object of the invention to provide a grain separatorcomprising a `plurality of slatted rollers in conjunction with gratesand constituting substantially flails which exercise a further threshingfunction inder and concave.

Further objects and advantages of the invention will be set-forth in thedetailed description which now follows.

ln the accompanying drawing Figure 1 is a view of a :grain separatorconstructed in accordance with the invention with one of the side wallsof the box or cas ing removed and with certain of the parts in section.

pulleys 21 and 22 from a shaft 23. This Y shaft carries the maindriving' pulley 24 through which power is applied to all `of themechanism contained within the separator and baler. Shaft 23 carries apinion 25 which meshes with the gear wheel 26 upon shaft 27. Shaft 27carries a pinion 28 which ineshes with the gear wheel 29. This gearwheel carries a wrist pin 3()` to which one end of the connecting` rod31` is pivoted. The opposite end of this connecting rod is pivoted at 32to the usual plunger 33 of a baler which comprises thebaling box 34.Mounted in bearings 35 carried by the baler box isa shaft 36. This shaftcarries a seginental gear wheel 37. provided at desired intervalsf withteeth 38 which act intermittently upon teeth 39 of a shaft 40. Securedto this shaft is a feeder arm 41a, the curved free end 42a of whichswings downwardly into the baler box to pack the straw vin front of theplunger in a inanner which will be readily understood. Projectingrearwardly from shaft l0 is an arin Lllwhich carries a weight 42. VA rod43 is pivoted to this weight at del and is slidably mounted within ayole 45. A spring 46 bears between the head 47 of this rod and the frontend of the yoke. The opposite end of the yoke is pivoted at L19 upon Vanear 50 carried `by the top of the baler box. A. chain or belt 51,

as desired, passes over a pulley 52 which is formed with the segmentalgear 37 and serves to impart nioveinent to said segmental gear froin apulley icarried by gear 29. Formed in the side walls of the casing 5 areopenings 58 through which the usual blocks 59 may be insertedwhendesired, these being the blocks that are coininonly employed in balersto back up the ends of the bales of straw. Slatted rollers 60, 6 1 and62. which comprise end disks 63 and slats 64 are mounted as illustratedin Fig. 1 to coperate with grates 65 and 66. The grain as 1t passesyover these grates and through these slatted rollers is subjected to athreshing ac- Vtion' much like that of a flail.

The slatted roller 60 ismounted in arms 67 which are pivoted at 68 tothe frame 7. Rods 69 are pivoted at 70 to the frame 7 and pass throughthe tail'ends71of the rods 67. Springs 72 bear between portions of theserods 69 and Vthe tail ends 71 of rods 67 and normally tend to elevatether slatted roller 60. By virtue of this construction a floatingmounting for this slatted roller is provided which vaids in permittingthe ready entry of the grainl therebeneath. lf found toV be desirable, abaille plate 73 may be employed to `.160 and 62 lie aboveV the gratos.

' imparted to roller 61 in the direction of the further aid inpreventing the passage of too great a quantity of straw beneath rollerY60 at onetime. Rollerf61, it will 'be noted, is journaled Vbeneath thegrates, while rollers Motion is Varrow thereon by a crossed belt 74 andpulleys 75 and 76. Motion is imparted to roller 62 from roller 61by'means of a crossed belt 77 and pulleys'78 and 79. Motion isimpartedto roller'60 from roller 62 by means of belt 80 and pulleys 81and 82. The peripherics of rollers 60l and 61 are comparav tively closertogether, much closer than the vdistance from the periphery of roller 62to grate 66 but roller`62 is not only larger in diameter but the size ofthe pulley is such that its speed is greater than the speed of roller61. T he'action upon the straw as it passes between rollers 60 and 61 isa beating action, while( the action upon the straw as it passesV roller62 is not only a beating but is also a rubbing action due to theincreased 90 and 91', mounted upon the shafts 92 and 93 of rollers 84and 88 respectively. The shaft 93 isin turn driven by a crossed belt 9stand pulleys 95 and 96 from the gear vwheel 29. A' deflector plate 97 isarranged at the front end of the conveyer 83 and its discharge endoverlies a screen'98.\ This Y screen-has its discharge end 99 disposedover Ya'deflector plate 100 the discharge end of which is located abovean auger 101 which operates in a trough 102 to'feed the tailingslaterally through the side wall of the casing 5 and'upon a tailingelevator comprising an endless belt 103 and rollers 104 and 105 by whichthe tailings are elevated to a point within the housing 106 where theyare discharged upon auger 107 which carries them laterally far enough todischarge them upon a second conveyor 108 which passes over rollers 109and 110. A spout 111 directs the tailings as they fall over the lastnamed roller to a point where they will be again fed beneath thecylinder 18 and the threshing operation will be entirely completed.Roller 101 is driven by a crossed belt 112 and pnlleys 113 and 114 fromthe shaft 115 of roller 87 while the auger 101 is driven by a belt 116and pullcys'117 and 118 from the shaft of roller 101. A pulley 119drives through a belt 120 to a pulley 121 on shaft 122. This shaftcarries an eccentric 123 through which a shaking movement may beimparted te screen 98 and, if desired, the rear end of this screen maybe mounted upon a roller 124 carried by frame 7. A fixed screen 125 islocatedbeneath the screen 98 and its discharge end overlies a grainauger 126 which operates in a trough 127 and this grain auger dischargesthe cleaned grain ready to be sacked laterally and the auger 126 isdriven by a belt 127 from a pulley 128 on shaft 122. This shaft 122likewise carries a pulley 129 which drives a pulley 130 on shaft 131 ofa fan 132. This fan is mounted in a casing 133 and the blast from saidfan is directed upwardly and rearwardly between the screens 98 and 125.A crossed belt 13%1 and pulleys 135 and 136 provide means for drivingthe shaft of roller 10 from shaft 138 of roller 85.

Operation.

The grain is fed into the machine over table 8, the feeding actionheilig aided by the endless carrier 9. The band cutter 12 severs thebands and the grain is fed between the cylinder and concave in the usualand well known manner. After being subjected to the usual threshingaction at this point, the grain is subjected to a further threshingaction by passing through the slatted rollers and 61 and is thensubjected to a further threshing action by passing between roller 62 andgrate 66. rlhe straw from which the grain has been threshed isdischarged over the ends of the grate 66 into compartment 5a of casingv5 where the feeder 42 of the baler acts intermittently to thrust itdownwardly inv front of the plunger 33. This plunger slowly reciprocatesunder the action of the gears 25 to 29 and connecting rod 31 and balesthe straw in the usual and well known manner. lAs the feeder of the haybaler travels downwardly to thrust thcJ straw into the baler box 34 itwill be apparent that the weight 42 will be lifted and the spring 46will be placed under tension. After the teeth 38 move out of engagementwith the teeth 39 the vspring `starts the feeder lil and 42 upon itsreturn or'upward movement and toward the conclusion of such upwardmovement and as the action of the spring begins to weakenthe weightmoves into position to becomeeffective and complete the return movementofthefeeder. The threshed grain falls through the grates and is carriedin the direction of the'farrow o by the Vconveyer 83 and it isdischarged upon deiiector plate 97 and conveyed to screen 98. llhe bulklof the grain passes through this screen and falls upon vscreen 125 andis conveyed by screen 125 to grain auger 126 which is the usualdischarge auger of the machine. There is, however, a certain amount oftailings or unthreshed heads ot grain and the like which passes in thedirection of the arrow 5 over the right hand end of screen 98 and overdeiiector plate 100 to auger 101, these tailinos bein discharged b saidauoer u on c r9, a o

the elevator 103 and conducted by said elevater and its associated partsto spout 111 and discharged in front of the cylinder and concave toagain undergo a threshing operation. As the grain falls from screen 98to screen 125 the fan acts to blow the chai' therefrom and dischargesaid chaii" upon cha-ii elevator 86. rlhis elevator conveys the chaii tocompartment 5a and it falls into the baler and is baled in the straw.While the blast ot air from the fan is sucient to carry the very lightchai' over upon the chart elevator it is not suliicient to disturb theproper course 'of the tailings from the right hand end of screen 98.
